Patented Dec. 15, 1914.

Original application filed June 23, 1908, Serial No. 439,967. Divided and application filed June 3, 1909, Serial No. 499,875. Renewed October 8, 1914. Serial No. 865,772.

To all whom it m (13 concern Be it known that I, lllARSHMAI-N W. Haznx, a citizen of the United States, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Ribbon Mechanisms, of which the following is a full, clear, and exact description.

This invention relates more particularly to the ribbon mechanism of visible frontstrike typewriting machines, and is a division of my pending application, Sr. No. 439,967, filed June 23, 1908.

The. primary objects of the invention are to provide simple and etlicientmeans wherethe ribbon may be properly held adjacent to the face of the platen and so operated that it will be automatically moved away from the printing point immediately after the printing takes place; and to provide means whereby the ribbon is adapted to be vari ously adjusted relatively with respect to the platen so that the ribbon may have a plurality of colors thereon anyone of which may be readily placed in operative position for changing the color of the writing.

Another object of the invention is to provide a simp J and efficient machine in which the ribbon mechanism may be mounted upon the carriage support in such a way that the carriage support may be folded over above the keyboard without at all interfering with the operative parts of the machine, so that as soon as the support is again placed in position for use, the ribbon mechanism may be properly operated through the key-levers.

A further object of the invention is to provide simple and eflicicnt means whereby the ribbon may be made to move in either direction acro s the machine, and to provide means whereby substantially the entire surface of the ribbon may be utilized.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification. and will then be pointed out in the claims at theend of the description.

In the drawings, Figure 1 is a longitudinal section of one form of'machine cmbodying my invention, showing part of the mechanism in elevation. Fig. l is a frag incntary vertical section showing one of the corner posts or slides for the carriage and the guide for said slide. Fig. 2 is a detail inverted plan of the carriage, support and mechanism mounted thereon detached from the machine. F ig. 3 is a fragmentary front elevation of the upper part of the machine, showing in elevation, the means for vibrating the ribbon adjacent to the printing point. Fig. l is a fragmentary inverted plan showing a partof the means for adjusting the movement of the ribbon. Fig. 5 is an enlarged elevation, partly in section, of a part of the ribbon operating mechanism. Fig. 6 is an enlarged section, partly in elevation, of one of the ribbonspools; and Fig. 7 is a fragmentary sectional plan showing the worm and worm gear for rotating the rib bon spools.

The frame 10 may be of the usual or of any preferred construction, and extending transversely thereof are a plurality of rods 11 to which the key-levers 12 are pivoted, and these key-levers form a part of a universal or standard keyboard and at their inner ends may be connected by links 13 to the tyne-bars or carriers 14. These type-bars 14 may be pivoted to a bracket 15 at one of their ends and at their other ends may have type-heads 16 on which are a plurality of characters indicating the upper case, the lower case and the figures, and these typeheads are adapted to engage the work sheet held about a platen 17 which may be supported to rotate in a carriage 18, the'latter being movable lengthwise of its bed 19. i

The carriage may be operated by any suitable mechanism and may have its support adapted to be folded over, as shown in dottcd lines in Fig. 1, all of which may be of the usual or of any preferred construction.

To operate the ribbon and to adapt the same to be shifted with respect to the type so that a ribbon having more than one color may be employed or the entire surface of the ribbon used. a plurality of ribbon spools 20 and 21 are arranged upon the carriage bed so as to be elevated therewith. These spools are each held to rotate with or independently of a sleeve 22. A shaft or spindle l3cpasses through each sleeve and these spindles are fixed to the arms Z-l, the latter being pivotally held to bars 25 located on opposite sides of the machine and forming a part of a vertically movable support. Each sleeve is or device 53 carried by the transverse bar 54 ot a rocking frame of which the arms e2 threaded at its upper end, as at 26, on which is arranged a tliuinbanit 2? which is adapted to engage the flange of pool and force a part of the some into enga ement with the shoulder 29 or the sleeve whereby the spool may be made to rotate with the sleeve oi independently 4 thereof, according to whether the thumb-nut- 27, l i 5 and 6, is tightened or roles; The ribbon 30 is held between the movable flange 28 of the spool, and the stationary flange 31, and one end of said ribbon may be fastened to the sleeve part 32 each spool. Each flange 31 is supported by bracket- 33 secured to one of the arms 911-, and is provided with a ribbon guide 3%. This guide is in the form of a loop having a slot at one side, as at 35, through which the ribbon may be passed, and said loop may be arranged in a substan tially vertical plane. Each sleeve is pro vided with a gear which is engaged by a worm 37 mounted to rotate in a bracket 38, and on the spindle or shaft 39 of each worm is a ratchet wheel 40 which is engaged by pawl 41 carried by the upper end of each leyer or arm 42, so that when said lever is moved, the pawl will be made to impart a step-by-step inoven'ient to the worm and the ribbon whenever any of the key-levers ar depressed, as will be presently described, the said ratchet wheels each being engaged by a spring-pressed pawl or detest to prevent the ratchet wheel from moving except in one direction. As will be seen, the gears 36 are both moved when the ratchet wheels 40 are operated through the move, ment of the arms or levers but on the return movement of the levers, and only that spool is operated in wllch the nut 27 has been tightened to cause the spool to rotate with the sleeve 22, the ribbon thereby being made to move in either direction according to which spoo is loose on the sleeve and the other tightened.

The ribbon extends inwardly to the front part of the platen as shown best in Fig. 2, and is pa sed through the loop or slotted portion 3% formed in the end of a vibratory arm This arm 15 is pivoted at 46 to the inner edge of the carriage bed, and has a tooth or shoulder portion H} which is engaged by one end of a bell-crank or angular lever 48, and said arm is normally forced in one direction against the action of the lever 48 by means of a spring which is attached to the lever at one end and to the carriage bed at the other. The lever 48 is pivoted at 50, and has its arm 51 adapted to strike a stop or projection 52and its outer end arranged in the path of a movable slide form a part and which are rigidly connected to said her This device is shdingly held upon the. bar 54, and is l mited 1n its moveinent along the same in one direction by a collar or par 55, and in the other direction by pin 56 carried by said bar. The devic 58 is substz'intially U-sl'iaped in form, and provided with downwardly projecting lug 57 through which is passed a screw to hold the same to the transverse bar 5 The device 53 is provided with a projecting part 59 serving as a handle to move the slide, and on the outer surface thereof has a part forming a cam surface 60 which may be integral with said device or slide. By moving the device to cause the cam portion 60 to engage the end of the arm 51 of the lever 48, the throw of said lever 48 may be varied and thereby the movement of the vibratory arm 45 carrying the ribbon. The movement or" the device is arranged to adapt the ribbon to print two different colors, so that by movins; the slide one way its extreme throw will cause one part of the ribbon to be engaged by the type, and it moved in the other direction the other color of the ribbon may be used, and at each movement of any of the hey-levers to be described later, the said device will vibrate the ribbon laterally for printing purposes, and as soon as the keyleveis are released, the spring 419 will return the vibratory arm to its normal position ontirely free and below the printing point to permit the writing to be seen immediately.

By sliding the device 53 between any of the two extremes, a graduated movement of the ribbon may, be 'iven, thereby permitting the entire surface of the r' abon to be used and thus materially saving the wear of the same, the end of the arm 51 of the lever 48 being so positioned that the slide or device f3 will have a certain movement before engaging the lever 18 in order that the vibratory arm may always be returned by the spring 49 below the printing point Whatever the position of the device 53 may be.

The bar is held in the upper end of the arms or levers e2 which are pivoted on opposite sides of the machine toa transverselyeritending re or bar 61,; and in the upper end of each or said arms 41-2 is a vertical slot 62. *bell cranlt or angular lever 63 is pivoted at (it to a part of the machine frame on each side thereof, and has one end, as by a screw 65, guided in the slot 62 of one of the arms 49 and its other end connected by a linl: or red 66 to a universal bar 67. This universal bar 67 extends transversely of the machine over each key-love; so that as each kej-lever is depressed, it will raise the bar 67 and move both of the bell-crank levers 3 on their pivots 64, and by means of the shoulder screws in thelslots 62 of the arms 42 Will throw the bar 54 outward and thereby move the device 53 to operate the bell-crank lever 48 and through it vibrate the arm 45 and ribbon and on the return movement of the arms the pawls d1 can ried thereby Will impart a movement to the ratchet Wheels 40 to shift the position of the ribbon lengthwise of the platen and in a direction depending on which not ET is tightened as already explained.

The levers or arms 42, Fig. 1, may be forced inward by the springs 68 which are held at one end to the rear part of the frame and engage the arms 42 at their free ends. An adjusting screw 69 is adapted to engage each spring 68 and serves to vary the pressure of the springs against the levers 42, and by means of the bell-era. k lovers 63 and links 66 the universal bar 67 will be forced against the action of the key-levers with any desired pressure. This action of thesprings 68 not only serves to permit the force required .to operate the type-bars to be changed. but they serve to restore the typebars and key-levers to their normal position, and if desired other springs for each keylever may be dispensed with.

An arm 70 may be connected to the transverse rod 61 and this arm may be operated by a shift lever 71. which is held to the transverse rod. 7'2 of a suitable platen shift mechanism so that the carriage and platen as well as the ribbon mechanism may be moved vertically and maintained in operative cooperation with the key-levers whatever the vertical adjustment may be. When the carriage is folded over as shown in dotted lines in Fig. to make the machine more ciiimpaet, the r .bon spools and ti on rotating; mechanism as well as the bell-crank lever a3 and arm l for vibrating the ribbon laterally will be folded also. which will carry the ratchet wheels 40 away from the pawls 41, and the bell-crank lever 48 away from the dev ico 5 :3 of the rocking frame, but soon as the carriage is restored to its normal working position, the mechanism for moving the ribbon lengthwise of the platen and "for vibrating the ribbi'in laterally will be automatically placed in position to be operated by the key-levers. The rocking frame remains in operative relation with tl'le'key-levers at all times and by reason of the slots (39 in the arms 42 the said arms may be moved vertica v with the carriage and ribbon nirchanisni when the platen shift mechanism operated.

Vllilk? l have shown and described features of a typewritiii; machine other than the ribbon mechanism. such features as are not claimed herein are covered in m pending application hereinbetore referred to. or in. other divisional and co-pcnding applications.

From the foregoing it will be seen that simple and eliicient ribbon mechanism is provided whereby the ribbon may have a plurality of colors thereon: that said ribbon is so operated that it will permit visible Writing and may have substantially its entire surface used, thus materially increasing the life of the ribbon; that simple means is provided whereby the ribbon may be moved in either direction, and that said mechanism is so constructed that a part thereof may be folded over above the keyboard, to cause the machine to occupy much less space than when in use.
